On the other hand, pulmonary veins are large blood vessels that receive oxygenated blood from the lungs to delivery to the rest of the body. There are 4 total pulmonary veinsâwith 2 pulmonary veins coming from each lung, left and rightâthat empty into the left atrium of the heart.unction. While veins usually carry deoxygenated blood from tissues back to the heart, in this case, pulmonary veins are among the few veins that carry oxygenated blood instead. Oxygenated blood from the lungs is circulated back to the heart through the pulmonary veins that drain into the left atrium.
Since the time of the red scare led by Joseph McCarthy, the term McCarthyism has entered the American vernacular as a general term for the phenomenon of mass pressure, harassment, or blacklisting used to instill conformity with prevailing political beliefs.
Although the name McCarthyism is given to all of the anti-communist activities in the U.S. during the 1940 s and 1950 s, this is technically a misnomer because the Senator from Wisconsin did not start the movement. n the 1940's and 1950's, an anti-Communist movement swept the United States of America. Fueled by the anti-Communist actions of Congress, particularly a Senator from Wisconsin by the name of Joseph McCarthy, the movement escalated and many people lost their jobs as a result of various blacklists.
